James Russel Miller
If you will call your troubles experiences, and remember that every experience develops some latent force within you, you will grow vigorous and happy, however adverse your circumstances seem to be.
Henry Miller
Greece is the home of the gods; they may have died but their presence still makes itself felt. The gods were of human proportion: they were created out of the human spirit.
George Polya
A great discovery solves a great problem, but there is a grain of discovery in the solution of any problem. Your problem may be modest, but if it challenges your curiosity and brings into play your inventive faculties, and if you solve it by your own means, you may experience the tension and enjoy the triumph of discovery.
